Yeah it would be good to know if this was actually discussed with RSSAC to save the co-chairs some time of having to go back to them although I understand that board may want to engage with CCWG directly (to avoid unecessary hear say...)
I guess confirming that the RSSAC gives a nod on this is the most important. As to .INT i guess we should not delve into that here as its been discussed within CWG and put to a proper rest.
That said, and just for note, i have no strong feeling about what i am about to say hence may not need to be considered; from the first part of Bruce statement, i think combining domain name system(DNS) with "root name server system" seem not to flow quite well. So i am wondering if the following would help:
"Facilitates coordination of the operation and evolution of the DNS of the(or within the) root name server system."
